This is a list of processed foods by type (not by brand). It is not a complete list. Many new food products are marketed every year.
You can evaluate how processed a food is by reading the label's ingredients list to see the names, number, and type of ingredients. A large number of ingredients, with names that you don't recognize, indicates a highly processed food.
More generally, virtually every food that has a label is processed. Virtually every food that comes in a box, bag, jar, or can is processed.
For more information see the pages on processed food and whole foods.
